VReferring now to the'drawings, wherein 4 like reference numerals designate like parts 25 plate formedv of any desired material and upon the front and rear faces of which the entire operating mechanism is preferably mounted. f

A 'manually operable lever 8, which will hereafter be referred to as the initiating lever, is pivoted intermediate itsends `as at 9 on the rear of the platein'slightly spaced relation thereto. One end'offthis ylever projects out Y wardly through a slot 10 in casing 7 and in cludes a nger ring 11. rl `he opposite end of the `lever extends inwardly andis shaped to provide an arcuate lug or extension 12. A pin 13'is fixed iu the path of the lever to check its upward oscillation. The mechanism to be actuated by the initiating lever will` now be described., i

A normally horizontallever 14' is mounted to oscillate at one end Ona fixed pivot 16. Its

. opposite movable end has Van uprightl link More specifically, this v`invention is connected with linkl 17h37 a 19111122?- throughout the severalviews, 6 indicates a as at 24' and its upper end free tov oscillate between the arms of a vguide member 26? ofany suitable' form. Lever 23 is provided with an incisiouwhich terminates in an arcuate recess 27-of the same general size and shape as the contourof lug 12 on the initiating lever.. A-

flat spring 28secured to the recessed side of the lever .as at 29 always engages a portion of lug 12 and mayor may not prevent the engagement of -lug 12 with recess 27, as will later be described. In the full line position shown, the moment ofthe inner end oflever 8*, iaided by the resultant force exerted by spring,(not shown) may be utilized, if desired, to more positively throw the lever 8 into its full line position.

Adjacent the inner sidelof lever 123 is a Vguide for the insertion' of a coin C.: This75 2) and thereafter permitted to Vdropfthrough 3.5:

slot 30 to the rear side of the plate.l A dog 31, substantially'parallel to lever 23, is mounted on afiXed pivot 32 intermediate its ends.- A tension spring 33 tends to oscillate the dog, which oscillation is checked at; a predeter mined pointby a stop lug 34. The upper end of the dog is disposed adjacent to and below the coin slot and is provided with an inset surface 36 for engaging the peripheryof the coin, a shield or guide member 37 for guiding the coin and maintaining it in the plane of insertion, and a shoulder 38 for limiting the downward movement of the coin. When there is no coin between lever 23 and dog 31, it will be seen that, fiat spring 28 having suiiicient resistance, the lug 12 cannot, by manipulation of lever 8, be caused to enter arcuate recess 27. The lug will merely slide over spring 28 and pass the recess and oscillate lever 23 independently of the other elements. However, when--a'coin is in place (as shown in full lines) and in resilient engage-` ment with the lever 23 and dog 31, spring 33 being stronger than iiatspring 28the latter spring is flexed by lug 12 when Vlever 8 is manually oscillated and the lug enters recess 27, thereby liftinglever 23.` The upward movement of lever 23 oscillates lever 14 which in lturn rotates disc-.19Y through link 17 and disc arm21.v -g

The disc 19 is provided-withperipheral I teeth 39.Y A rotary valvef40 -of any selected conventional construction: isV mountedy justy aboveV disc 19 iii a liquid'supply line 41. IThe plug 42 of this valve carries a cog wheel-43 which: meshes with t-he teeth 39 of disc 19, from which it results that the valve is operated by they disc. rlhis valve is normally closed (full line position of mechanism) and is opened .when the mechanism is actuated in.

the manner set forth in the precedingparagraph. Pipe line 41 receives a liquid, such as ginger ale under high pressure, and conveys it, when valve is open, into a closed measuring tank 44. The lower end of this tank opens into a discharge valve 46 ofthe same general construction as valve 40. Itsy rotary plug47 carries anoperating arm 48, which arm projects intothe path of a pin 49 on link 17 to be positively actuated thereby. Artension spring 50 resists the actuation of thev arm and tends to retain it in normal full line position, in which position the discharge valve is open. A discharge pipe lconveys thel'iquid from' valve 46 to a drinking receptacleina manner later to be described.

. A tension spring 52, secured to link 17 as at 53 andto'the plate 6 as at 54, tends to maintain link 17, and hence the entire mechanism thus far described, in its lfull line position. At the upper end of link'17 a bracket 56 is` mounted to carry a roller element 57. This element necessarily travels in a fixed path when the initiating lever is operated, and a locking member 58 is arranged in this path on a'pivot 59; A spring 60 resiliently holds locking member 58 in engagement with a stoppin 61'.. Thelower portion of the locking member is providedwith aV recess 62 roller element 57 on link 17, when the latter y reaches the upper limit of its path. The locking member is provided with a tripping extension 63, which, when lifted, will release the roller element and permit it to be drawn downwardly by spring 52. Extension 63 has a slot 64 which permits the locking element to be oscillated about it-s pivot 59 without engaging a vertical guide'rod 66 which is mounted centrally of the measuring tank 44.

lVithin the measuring tank a float 67 is arranged and provided with a central vertical bore for receiving the guiderod 66. rilhis oatvmay be made hollow or of solid impermeable material, but in either event its the tank by way of pipe 41. Slidably mountned on the guide rod above the float is an externally threaded sleeve 68 which in turn receives an internally threaded bushing" 69. It willl be seen that as float 67"rises it lwill force the sleeve and bushing upwards to cause ythe latter to strike the tripping eXtension 63 and lift it. A lock nut 70 is threaded on sleeve 68V so that the combined llength of the sleeve and bushing may be adjusted and setto any desired value, thus to regulate the amount of Vliquid which may enter the tank before tripping the locking member and releasing the' mechanismv held thereby,

VHorizontally disposed adjacent the upper side of the disc 19-and parallel thereto is a horizontally movable bar 71. One end of this b-ar is slidably received inl a guiding bracket 7 2 and the other end is bifurcated and carries a vertical bolt and nut structure 73.' A meinber 74 is secured on the vertical bolt withinV the bifurcation of the `bar and projects forwardly through a horizontal slot 76 to the front side of plate. The slot 76 is of sulii'- cient length to permit the member 74 to move longitudinally thereof `as-the bar is reciprocated. Near its bifurcated endthe bar 71 is provided with a stud 77 which, on the side adjacent the'disc, provides a pivotfor one end of an actuating link 78 which is parallel to the bar 71. The vfree end of this actuating link is shaped on its under side to vprovidean arcuate recess 7 9 andv a cam 80. A short pin 81, upon which link 78 rests, is mounted f near the periphery vof the inner side of the disc, .Said pin normally Yengages cani 80 and is adapted to slide 0E said cam into recess 7 9 when the disc is oscillated bythe operating mechanismin the manner already described. During such oscillation the pin 81 cooperates with the recess to force link 78, and hence bar 71 and member 74, to the left (Fig. 1). When member 74 has about traversedY the length of slot 76 another pin, 82, also carried by the disc closer to its periphery than pin 81, and spaced from pin 81 a distance substantially `equal to that between recess79 andv cam 80, engages the cam 8O to y lift the corresponding end of the link and remove the recess from engagement with pin 81. When this happens a spring, embodied in the cup dispenser presently to be referred to, thrusts bar 71 and link 78 back toward their original positions.

` Operation The device isset up with its pipe 4:1 connected to a source of liquid supply `and with its front face exposed to the View of thirsty and prospective customers. When a cus'- toiner inserts a proper coin in the slot and throws the lever 8 from its full to dot-ted line position, he need but waitfor a moment and without further eii'iort a drink willbe served. Y

Lug 12 of lever 8 presses iiat'spring 28 inwardly, engages recess 27 and lifts the elements 28, 14, 17 and 57 upwardly until roller 57 is received by, and latched within, recess 62 of locking member 58, as shown' in broken lines in Fig. 1. Simultaneously'the coin is rolled upwardly along dog face 36 by lever 23 and reaches its dotted lineposition at the same moment that roller 57 becomes latched.,

at which time, due to the resilient action of spring 33, the coin is ejected through ahori- Zontal slot 96 in the lower end oflever23, to a suitable receptacle in the bottom of the casing 7L As link 17 is `moving' upwardlyits lug 49 strikes lever 48 and closes valve 46l against the action of spring 50, and its upper end rotates disc 19. During the first part of the rotation of disc 19 its pins 81 and 82cooperate with recess 79 and cam 8O to cause bar 71 to operate the cup mechanism and deposit a cup. At the saine time the disc begins to open valve 40 and as it reaches its final dotted line position it has caused the valve 4() to become fully opened. Now, with the parts v inthe positions just attained,'therbeverage flows through valve 40 into measuring chamber ill and causes the iioat 67 Ato rise until,

when exactly one cupful of liquid has entered f the chamber (predetermined by adjustment into pipe 51 and thence into the discharged cup. The drink has been served and the machine is now ready to perform another cycle of operation.
